Struts2 与 freemarker 生成Json、XML 的模板

必须加入的包有jsonplugin-0.30.jar,xsttream-1.3.jar,freemarker-2.3.8.jar

Xml代码

1. ///struts.xml 
2. <struts>
3. <include file="struts-default.xml"/>
4. <package name="json" extends="json-default">
5. <action name="extjs" class="book.action.ExtjsAction">
6. <result type="json"/><!-- 这里生成Json -->
7. </action>
8. <action name="extjsXml" class="book.action.ExtjsAction">
9. <result type="freemarker">
10. <param name="location">template/gridXml.ftl</param>
11. <param name="contentType">application/xml</param>
12. </result>
13. </action>
14. </package>
15. </struts>

///struts.xml
<struts>
    <include file="struts-default.xml"/>
    <package name="json" extends="json-default">
        <action name="extjs" class="book.action.ExtjsAction">
            <result type="json"/><!-- 这里生成Json -->
        </action>
        <action name="extjsXml" class="book.action.ExtjsAction">
            <result type="freemarker">
	            <param name="location">template/gridXml.ftl</param>
	            <param name="contentType">application/xml</param>
            </result>
        </action>
    </package>
</struts>

模板如下，

Xml代码

1. //src/template/gridXml.ftl 
3. <?xml version="1.0" encoding="utf-8"?>
4. <list>
5. <Total>
6. <results>${results}</results>
7. </Total>
8. <#list items as item>
9. <#assign recordName=item.class.name.replaceAll(".*\\.","")>
10. <${recordName}>
11. <#assign methods=item.class.declaredMethods>
12. <#list methods as method>
13. <#assign isGetMethod=method.name.startsWith("get")>
14. <#if isGetMethod = true>
15. <#assign methodmethodName=method.name.replaceAll("get","").toLowerCase()>
16. <${methodName}>
17.                 ${method.invoke(item,null)} 
18. </${methodName}>
19. </#if>
20. </#list>
21. </${recordName}>
22. </#list>
23. </list>
